Parasitic computing involves solving large problems across various physically separated web servers to take advantage of distributed computing power. While TCP checksums help detect corrupted messages during transmission, internet-wide parasitic computing is only a theoretical consideration currently due to communication delays outweighing computation benefits and security risks to target nodes. For parasitic computing to be practical, the communication to computation ratio would need to be high enough to blur the line between the two.

Tcp and udp
TCP guarantees reliable delivery of data packets in the correct order, while UDP does not provide these guarantees. TCP is commonly used for applications that require reliable data transfer like HTTP and FTP. UDP is used for applications that prioritize speed over reliability, such as media streaming, VoIP, and online games. While TCP ensures error-free transmission, it introduces more overhead and latency than UDP. The choice between TCP and UDP depends on an application's requirements for reliability versus speed.
Delay , Loss & Throughput
Delay refers to the time taken to transfer a message from sender to receiver. It is calculated based on processing delay, queuing delay, transmission delay, and propagation delay. Packet loss occurs when a router's queue is full and it must drop packets. Bandwidth is the maximum rate of data transfer, while throughput is the actual rate of successful data transfer from one point to another.
File Transfer Protocol - FTP
FTP (File Transfer Protocol) allows users to transfer files between two hosts on the internet. It has two types of connections - a control connection that transfers commands and a data connection that transfers files. FTP clients allow users to connect to remote hosts, upload and download files using FTP commands. Some advantages are speed, efficiency, security, and ability to transfer files back and forth. Disadvantages include lack of encryption on some providers, file size limits of 2GB, clear text passwords, and incompatibility with some systems.
Network protocol
This document summarizes a seminar presentation on network protocols. It defines what a protocol is and discusses some common network protocols like TCP, UDP, HTTP, and Ethernet. It also covers different types of network protocols including Ethernet, LocalTalk, Token Ring, FDDI, and ATM. Benefits of using network protocols include standardized communication between hardware and software. Protocols are needed for computers to effectively communicate over a network.

IP Datagram Structure
The Internet Protocol (IP) is the fundamental protocol that defines how data is sent between computers on the Internet. IP addresses uniquely identify each computer and data is sent in packets that contain the source and destination addresses. Packets can take different routes and arrive out of order, with TCP ensuring proper ordering. IP is connectionless and sends each packet independently. The most common versions are IPv4 and the newer IPv6. The IP datagram structure includes a header with fields like version, length, checksum, and source/destination addresses, followed by the data. Large data can be fragmented into multiple packets for transmission.

The document defines HTTP and HTTPS. HTTP is the Hypertext Transfer Protocol that provides communication between web browsers and servers. It is unsecured and transmits data in plain text. HTTPS is HTTP secured with SSL/TLS encryption to provide security. Key differences are that HTTPS uses port 443 instead of HTTP's port 80, establishes an encrypted channel, and verifies servers with certificates to protect against attacks.
Congestion control, slow start, fast retransmit
This document discusses TCP congestion control algorithms including slow start and fast retransmit. It provides overview and explanations of how these algorithms work to control congestion in a network. Slow start gradually increases data transmission to find the network's maximum capacity without overloading it. Fast retransmit allows retransmission of lost packets upon receiving three duplicate ACKs without waiting for timers, improving efficiency. These algorithms help prevent network congestion and allow for faster data transmission.
Ftp
File Transfer Protocol (FTP) is a standard network protocol used to transfer files between a client and server. FTP is built on a client-server model and allows users to access files on remote systems. Key components of FTP include the client, which initiates file transfers, the server, which stores and transmits files, and the FTP site, which houses files and determines user access levels through usernames and passwords. FTP supports both anonymous access for public files as well as authenticated access through usernames and passwords for private files.
Basic Networking Concepts
This document summarizes different types of computer networks including local area networks (LAN), metropolitan area networks (MAN), and wide area networks (WAN). It also describes client-server and peer-to-peer network architectures, as well as common network topologies like bus, ring, and star. Additionally, it outlines different network communication technologies such as intranet, extranet, and internet. The document was created by Sehajbir Singh of Class VIII-E to provide an overview of computer network types, architectures, topologies, and communication technologies.
Mobile computing : Indirect TCP
Indirect TCP suggests splitting the TCP layer into two sub-layers: a TCPM connection between the mobile node and base transceiver, and a TCP connection between fixed nodes. The TCPM sends and receives packets to/from the mobile node via the base transceiver and to/from a TCPF layer at a fixed node. Selective repeat protocol modifies indirect TCP by using UDP for selective retransmission of data between the mobile node and base transceiver, while still using TCPM and TCP between network endpoints. Mobile-end transport protocol further modifies this by guaranteeing in-order delivery between the mobile node and base transceiver like TCP instead of UDP.
Transport layer
The transport layer provides efficient, reliable, and cost-effective process-to-process delivery by making use of network layer services. The transport layer works through transport entities to achieve its goal of reliable delivery between application processes. It provides an interface for applications to access its services.
File transfer protocol
FTP (File Transfer Protocol) is a standard network protocol used to transfer computer files between a client and server over a TCP/IP network. FTP uses TCP/IP to transfer files and allows users to exchange files between accounts, transfer files between accounts and desktop computers, or access online software archives. When transferring files, FTP facilitates either uploading files from a personal computer to a server or downloading files from a server to a personal computer.

Powerpoint for data communication
A computer network allows multiple computers to be interconnected via transmission paths like telephone lines. Data communication is the exchange of digital data between two devices via a transmission medium like wires. There are two types of data communication: local, for communicating devices in the same building, and remote, for devices farther apart. A data communication system must effectively deliver data to the correct destination, do so accurately, and deliver it in a timely manner. The five basic components of data communication are: the message being communicated, the sender, the receiver, the transmission medium connecting them, and the communication protocols governing the exchange.
Http Introduction
HTTP is the most popular application protocol on the internet. It uses the client-server model where an HTTP client sends a request to an HTTP server using a request method like GET or POST. The server then returns a response with a status code and can include a message body. A URL identifies a web resource and includes the protocol, hostname, port, and path. HTTP specifications are maintained by the W3C and the current versions are HTTP/1.0 and HTTP/1.1. The HTTP request and response include a start line, headers, and optional body. Common status codes indicate success, redirection, or client/server errors.
TCP Vs UDP
TCP and UDP are transport layer protocols that package and deliver data between applications. TCP provides reliable, ordered delivery through connection establishment and packet sequencing. UDP provides faster, unreliable datagram delivery without connections. Common applications using TCP include HTTP, FTP, and SMTP. Common UDP applications include DNS, DHCP, and streaming media.
An Introduction to Internet
The document discusses the origins and development of the Internet. It began in 1960 when DARPA funded research into connecting computers to exchange data even if connections failed. This led to the creation of ARPANET in 1969, connecting four military research centers. By the 1990s, the introduction of the World Wide Web transformed the Internet. The document also outlines how individuals and organizations in India access the Internet through various ISPs and technologies. It provides an overview of key Internet terms and protocols.
Business models for business processes on IoT
The document discusses business models for business processes on the Internet of Things. It covers key topics like IoT applications, business models, value creation using IoT, and business model scenarios for IoT. Business models need innovation to adapt to new customer access and interactions enabled by technologies like cloud computing and mobile communications. Value is created on IoT through addressing emergent needs, information convergence, and recurrent revenue from networked products. Example business model scenarios for IoT leverage data from multiple sources like sensors, M2M, and open data.
HTTP Presentation
HTTP/2 is an updated protocol that improves upon HTTP/1.1 by allowing multiple requests to be sent simultaneously over a single TCP connection using multiplexing and header compression. It reduces latency compared to HTTP/1.1 by fixing the head-of-line blocking problem and prioritizing important requests. Key features of HTTP/2 evolved from the SPDY protocol and include multiplexing, header compression, prioritization, and protocol negotiation.

Internet of things (IOT) | Future Trends
The document discusses the Internet of Things (IoT), which connects physical devices to the internet and allows them to collect and exchange data. It describes how IoT is used in various industries and will consist of 50 billion objects by 2020. Some key enabling technologies for IoT are discussed, including RFID, WiFi, barcodes, ZigBee, and smartphones. The document then covers various applications of IoT such as smart homes, connected cars, smart cities, bio-chips, and more. Issues and challenges with IoT adoption are also summarized.
Human Area Networking Technology
Ubiquitous services that are genuinely user-friendly to everyone will require technologies that enable communication between people and objects in close proximity.
Focusing on the naturalness, inevitability, and sense of security conveyed by touching in everyday life, which describes Human area network that enables communication by touching, which we call RedTacton.
Here, the human body acts as a transmission medium supporting IEEE 802.3 half-duplex communication at 10Mbit/s. The key component of the transceiver is an electric-field sensor implemented with an electro optic crystal and laser light.
Power constraints play a key role in designing Human Area Networks (HANs) for biomonitoring. To alleviate the power constraints, we advocate a design that uses an asynchronous time encoding mechanisms for representing biomonitoring information and the skin surface as the communication channel.
Time encoding does not require a clock while allows perfect signal recovery; the communication channel is operated below 1 MHz. The ultimate human area network solution to all these constraints of conventional technologies is “intrabody” communication, in which the human body serves as the transmission medium.
The concept of intrabody communication, which uses the minute electric field propagated by the human body to transmit information, was first proposed by IBM [1]. The communication mechanism has subsequently been evaluated and reported by several research groups around the world.

And, 100% of retailers surveyed consider “a single brand identity across channels” as important.
In order to move forward on the road toward a successful omnichannel experience, retailers need to take a step back and consider their current strategies, as well as hardware and software capabilities.
In this upcoming webinar, Nikki Baird from RSR will share insights from the June 2012 survey titled: Omni-Channel 2012: Cross-Channel Comes Of Age. Some of the topics she will cover include:
The new rules of cross-channel retail
The value of cross-channel shoppers
The Digital-Physical connection
The role of Marketing in the strategy mix
NCR will join the discussion by outlining the steps toward cross-channel success, illuminated through real-world case studies. Once merchants commit to a compelling and consistent cross-channel experience, they must follow through with superior data analysis and promotion optimization, facilitated with best-in-class point of sale (POS) solutions. With all the proper components in place, retailers will improve loyalty and profits by delighting customers, no matter which channel they choose.

The document summarizes key aspects of the transport layer, including the transport service it provides to upper layers, connection-oriented and connectionless transport services, and transport service primitives. It discusses transport layer protocols like TCP and UDP, explaining how TCP uses a three-way handshake to establish connections and addressing challenges like congestion control, delayed packet delivery, and host crashes.
UAV Data Link Design for Dependable Real-Time Communications
Communication over the kinds of Data-Links used for unmanned vehicles presents important challenges dues to the low bandwidth, intermittent, and lower reliability of these links. Classic network protocols such as TCP do not operate well in this environment forcing application developers to implement their own reliability and session management. This presentation describes he issues and alternatives.

The document discusses denial of service (DoS) and distributed denial of service (DDoS) attacks. It describes different types of DoS attacks such as sending malformed packets to exploit protocol or application flaws. It notes that DDoS attacks involve aggregating malicious traffic from many zombie machines to flood the victim with packets. Most defense methods focus on mitigating bandwidth consumption from packet flooding. However, attackers may also directly target applications to exhaust computational resources. The document proposes an acknowledgment-based port hopping protocol for secure communication between a sender and receiver that is resistant to such attacks.
Communication primitives
This document discusses two common models for distributed computing communication: message passing and remote procedure calls (RPC). It describes the basic primitives and design issues for each model. For message passing, it covers synchronous vs asynchronous and blocking vs non-blocking primitives. For RPC, it explains the client-server model and how stubs are used to convert parameters and return results between machines. It also discusses binding, parameter passing techniques, and ensuring error handling and execution semantics.
Fundamental Internet Concept
The document discusses several fundamental concepts of the Internet including:
1) The Internet backbone is formed by major networks owned by large ISPs that connect to each other across the United States and world, with redundancy allowing rerouting if parts fail or slow down.
2) TCP ensures reliable data delivery through stream interface, reliable connection startup and shutdown, and handling of overwhelmed routers, out-of-order packets, and duplicate datagrams.
3) TCP provides robustness through acknowledgements for every datagram, data resending on timeouts, and automatic adjustment of timeouts based on distance and current delays.
Topic 5- Communications v1.pptx
The document discusses communication in distributed systems. It covers topics like layered protocols using the OSI reference model, transport layer protocols like TCP and UDP, middleware protocols that provide common services, client-server communication using TCP connections, push vs pull architectures, types of communication like persistent vs transient and synchronous vs asynchronous, and remote procedure calls (RPCs) that allow remote functions to be called like local procedures.

This document discusses a novel receiver-based traffic redundancy elimination (TRE) technique called Prediction-based Cloud Bandwidth and Cost Reduction (PACK) for cloud computing environments. PACK aims to reduce bandwidth costs and server load by having receivers detect redundant data and send predictions to senders about future chunks. This avoids sending redundant data and allows receivers to locally store chunks instead of downloading them. The document evaluates PACK using video traces and estimates its potential for cost savings compared to traditional sender-based TRE and no TRE.

The document describes the design and implementation of an on-chip system-on-chip (SOC) interconnect using an i-SLIP scheduling algorithm. The interconnect uses a crossbar switch architecture to connect 8 devices on the chip. Each device has an input and output block that can store up to 32 packets to send and receive. The scheduler block implements the i-SLIP algorithm to determine which packets from the input blocks will be sent to the output blocks. The goal is to provide an efficient communication mechanism between the on-chip devices using a packet-based protocol over the interconnect.
Tcp vs udp difference and comparison diffen
The document compares TCP and UDP protocols. TCP is connection-oriented and ensures reliable, ordered delivery of data. It is slower than UDP but suited for applications requiring high reliability. UDP is connectionless and does not guarantee delivery, order, or error checking. It is faster than TCP but less reliable. Examples of TCP applications include web browsing and file transfer. UDP is commonly used for applications requiring fast transmission like games and streaming media.
Java Networking
This document discusses Java networking and the client-server model. It explains that Java socket programming allows sharing of data between devices using protocols like TCP and UDP. Sockets are bound to port numbers to identify applications. The client-server model involves clients sending requests and servers sending responses. Examples of Java code for a simple client and server are also provided.
Mobile transport layer .
The document discusses several mechanisms used in TCP for mobile computing. It describes:
1) TCP congestion control mechanisms like slow-start and fast retransmit/fast recovery which are designed to address packet loss. However, these can be inappropriate for wireless networks where packet loss is often due to errors rather than congestion.
2) Approaches like Indirect TCP, Snooping TCP, and Mobile TCP which modify TCP for mobile networks by splitting connections or having a supervisory host monitor the connection to enable local retransmissions and avoid unnecessary window reductions when the mobile host disconnects.
3) Other TCP optimizations for mobile like forced fast retransmit after handovers and transmission timeout freezing to avoid slow-start
MODULE-4_CCN.pptx
This document discusses a computer networks course taught by Dr. Shivashankar at RRIT. The course aims to help students understand networking concepts and protocols. It covers topics like network architectures, protocols at different layers, and basic network configurations. The document provides details of transport layer protocols like TCP and UDP, explaining their services, operation mechanisms, and applications.
06-Networks-Software.pdf
Network protocols are sets of rules that allow devices to communicate over a network by standardizing how data is transmitted and received. They provide a common language that defines formatting, transmission, and reception of data so that devices can interact regardless of differences in infrastructure, design, or standards. For communication to occur, both sending and receiving devices must support and follow the same protocol conventions. Standard network protocols enable connectivity for virtually all network users.
Unit 4
This document discusses several approaches to improving TCP performance over mobile networks:
Traditional TCP uses slow start and congestion control mechanisms that reduce efficiency over mobile networks. Indirect TCP segments connections and uses a proxy to improve performance. Snooping TCP buffers packets to enable fast retransmissions without changing endpoints. Mobile TCP freezes the sender's window on disconnection to avoid unnecessary retransmissions. These methods aim to isolate wireless losses from congestion responses and enable fast recovery from errors and handovers.
Transport Layer In Computer Network
The transport layer provides end-to-end communication over a network by providing services such as connection-oriented communication, reliability, flow control, and multiplexing. It links the application layer to the network layer and performs functions like segmenting messages and establishing connections between endpoints. Common transport protocols are TCP, which provides connection-oriented and reliable data transfer, and UDP, which provides connectionless datagram delivery.
TCP/IP
TCP is the major transport protocol that provides reliable data delivery over the unreliable IP protocol. It establishes virtual connections between applications on different computers to guarantee prompt and reliable communication without data loss, duplication, or reordering. TCP achieves reliability through mechanisms like acknowledgments, retransmissions, adaptive retransmission timers, flow control using windows, and three-way handshakes for connection establishment and closure. It also implements congestion control to avoid overloading networks during periods of high traffic.

Proposition of an Adaptive Retransmission Timeout for TCP in 802.11 Wireless ...
The Transport Control Protocol (TCP) is used to establish and control a session between two endpoints. The problem is that in 802.11 wireless environments TCP always considers that the packet loss is caused by network congestion. However, in these networks packet loss are usually caused by the high bit error rate, and the wireless link failures. Researchers found out that TCP performance in wireless networks can be highly enhanced as long as it is feasible to identify the packet loss causes; hence appropriate measures can be dynamically applied during an established TCP session in order to adjust the session parameters. This paper proposes an endto-end adaptive mechanism that allows the TCP session to dynamically adjust the RTO (Retransmission Timeout) of a TCP session; the server will have to adjust the timers based on feedbacks from clients. Feedbacks are piggybacked in the TCP Options header field of the ACK (Acknowledgment) messages. A feedback is an approximation of the time needed by the wireless channel to get the errors fixed. The mechanism has been validated using numerical analysis and simulations, and then compared to the original TCP protocol. Simulation results have shown better performance in terms of number of retransmissions at the server side due to the decrease in the number of timeouts; and thus lowest congestion on the wireless access point.
new data.pdf
Computer networks allow for the connection and communication between multiple devices. They consist of devices like computers, routers, and switches that are connected via various transmission mediums. The goals of computer networks include resource sharing, high reliability through file replication, inter-process communication between users located apart, and flexible access to files from any computer on the network. Transmission mediums can be broadcast networks, which transmit packets to all recipients simultaneously, or point-to-point networks, which connect only two sites and are more secure but more expensive.

Removing Uninteresting Bytes in Software Fuzzing
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
